Specification of Letters Patent.

Patented Aug. 27, 1907.

Application filed August 18,1908. Serial No. 331,182.

To 'it 'may oncem:

Be it known that 1 Winmx BLAnua citizen of the UnitedStates, residing at Wabbsseks, in the county ,of Jefferson and State of Arkansas, have invented cer- T :tain 'new'. and useful Improvements in Hair-Clippers, of which the following is a specification.l

This invention is designed to' supply a'hand ymachine i for clipping which will admit of' the. cutting Y siderable expense isentaed :15

L, operating handle and a series of interchangeable cuttingv .fflf3lades, the .construction being such as to admit of the if blades being easily and quickly substituted when required. without necessitating` the use of vtools of any and effecting the interchange or substitution of 'For a full description of the invention and the merits thereof and also-to acquire a knowledge ofthe details of construction'of the foreffecting the result,

reference is to` be had tthefollowing description and compliant-edema.; 1

l While the invention may be adapted toxdifferent and 'conditions bychanges in the structure and ldetails without departing from the spirit or essential regimes, heengaan the preferred embodi- 'ment' .ish shownin `the accompanying drawings, in

is- Iaperspective viewof a hair clipping machine enihodyingthe .invention- .2 is a longitudinal section of the machine. \Fig.3 is'a topl v`plan viewbf the machine having thev cap plate re.-v

moved and the'tubular portion at the rear of thestock in 'sectionrrV Fi'ga is a detail view offa cutter, parts `being broken to show more clearlyrpthe relative "j arraugemento the coperating elements. Fig.. 5 is a detail perspective 'view of the .relatively movable cutter land the lc'operating therewith, the severalbeing 1 v Corresponding and like parts are referred following description and indicated in'l all the ve'wsiof," .the drawings by the same reference i f 1n general appearance, the device approximates .the forni ofthe usual hand clipping machine.l The main frame or stock'l is provided with a' xed' handle 2, the forward;portionbeingI reduced lin thickness and r a shoulder 3 at rear which the movable ctr'tter operates.- l Y`A mortise `or opening 4 is provided in the front edge of thestock l and snugly receives av tongue 5 cfa removable'or interchangeable cutter 6. The front corners of the stock are cut away, as shown at 7, to form spaces to receive corresponding projections 8 at the rear corners of the removable cutter 6. The removable "cutter 6 is of a thickness corresponding to the front portion of the stock so that the upper and lower sides come fiush. Suitable means are provided for connecting the cutter 6 to the stock so as to prevent casual displacement or movement thereof, and, for convenience, sp ing catches 9 are employed and are let into recesses 10 fermed in the outer edges or ends of the cutter 6 so as `not to project therefrom and'be in the way,

the projecting ends of the catches 9 being of hook form and adapted to enter grooves or recesses 10 in opposite edges of the stock 1, the inner ends of `said grooves or' recesses 10n being deepened to receive the Abent lends of stops at the extremities `of the catches sol as to prevent `outward ldisplacement of the cutter 6. When it is required to removethe cutter 6so asto replace the same by another of different size, the forward ends of the stantially the same manner as theparts 1 and 6, the- ,cutter 12 having a tongue 13 to enter a mortise or opening 14 in the front edge of the plate ll and provided with rear extensions 15 to snugly iit in corner spaces 16 of said,plate1l, spring catches 17 at opposite ends ofthe cutter to enter grooves or recesses18 in opposite ends of the plate 11 in a manner similar to the operation of the catches 9. Thefspringvcatches 17 are let into recesses in the ends ofthe cutter12 so as to beout of the way.

The movable cutter corresponds in thickness f to the- .depth ofthe shoulder 3v and is` arranged to reciprocate upon the fixed cutter 6 and the reduced front portion of the stock. Slots 19 are provided in the plate 11 and receive posts 20 projected upward from the reduced portion ofthe stock` 1, the slotsl9lbeingsuciently long to admit of the movable `cutterhaving ample movement ,with'reference tothe relatively finned cutter inthe operation of themachine. v A notch 2l is formed in the rear .which pin the operating handle Joscllates. The rear .portion of the stock at the root of the fixed handle 2 is made hollowand receives a coil spring 26, a screw 27 and a plate 28. The screw 27 is threaded into the outer lend of theltubular p0rtion- 429 of the stock and against an end portion oi the spring 26, the Aopposite end exerts pressure against the operating handle 23 to norlinally hold the handles 23 and 2 separated at their outer ends. The inner end and the front portion of the tubular part 29 are opened to receive parts of the operating handle 23 adjacent to its center of oscillation. A cap ing a rear extension to overlap the hub 24 and pierced to receive the upper end of the pin 25, the projecting end Vof said pin being threaded to receive a nut 31 by means of which the cap plate is held in` place and caused to exert a greater or less pressure 'upon the -movable cutter to hold it in coperative relation with the relatively fixed cutter.

A hair cutter or machine constructed substantially as herein specified is adapted to operate in the accus,

tomed manner, that is, by gripping the handles 2 and l-Ater the selected cutters have been placed in position,

the parts are assembled and the machine ready for operation in the mannerwell understood.

` Havingthusfilescribed the invention,what is claimed asnew is: v

1.In='a lhair clipping machine, the.combination of a stock-having a portion thereof reduced in thickness, -a'

` lixed cutter detachably connected'to the edge of the reduced portion of the stock', a plate movably mounted upon 'the 'reduccdportion- 'orf'the stockyqa movabieutter detachably connected with the plate and cooperating-with :se/also the first mentioned cutter, and means for operating the plate.

2.l in -a hair clipping machine, the combination of a 40 stock having a portion thereol:` reduced in thickness, a

.plate movabiy mounted upon the reduced portion of the stock, the said plate and the edge of the reduced portion being formed with recesses, detachable cutters provided with extensions engaging the before mentioned recesses whereby they are secured respectively to the plate 30 extends over the front poltion oi the stock and protects the rear part oi the cutters, said cap plate havstock and the plate, and means for operating the plate.

3. In a hair clipping machine, the combination of n critter comprising complcmentni cooperating parts detachahly connected, 'one of said parts having a recess at 50 an intermediate point and having its ends notched while the opposite parvis providedwith a tongue designedv to enter the recess and with end projections entering the before mentioned notches.

4. In a hair clippinf,r machine, the combination of a cutter' comprising complementai coperating parts de- .tachably connected, one of said parts being.r provided-with a recess at an intermediate point and having its end portions notchcd, while the opposite part carries n tongue designed to enter the recess and is provided with end projections engaging the before mentioned'notches, and fastening members' for connecting the said p artsfwhen assembled.

5. In a hair clipping machine, the combination o f a stock havingY the cnd portions thereof notched, a remov- 65,

able cutter provided with end extensions engaging the before mentioned notches, and a second-cutter movnbly mounted upon the stockto cooperate with the first mentioned cutter.

(i. In a hair clipping machine of the, character specified, the combination of :1 cutter comprising complementari parts 'detachably connectedv` each of the parts having a corresponding recess, und catches fitted to one of the. parts and arranged in the recess thereof and adaptedpto have their projecting ends enter therecess of the other part.

In testimony whereof I :itx my signature in presenceof two Witnesses.
